4000 Nanotechnology Certified Under Counter Filtration System

  

Based on feedback from DOS facility management and medical personnel, the B. David Company was encouraged to develop a residential drinking water system that met the following requirements:

  • Third party certification to NSF testing standards of P-231, which is considered the definitive drinking water standard for virus and bacteria removal 
  • Environmentally responsible – no electricity, chemicals or water wastage
  • Very low maintenance – 15 minutes per year
  • Produced in the United States at an EPA inspected factory
  • Durable and long lasting

After extensive research, field trials, and development, we are pleased to announce that our 4000 Nanotechnology Certified Under Counter System has met and exceeded initial product guidance. Additionally, we added two extra certifications - NSF/ANSI 42, reduction of free chlorine, and NSF/ANSI 53, for Cryptosporidium removal and lead reduction. We believe that this purifier is the most technologically advanced and field proven system available.

Benefits:

  • *Third party certification through IAPMO, North America’s premier plumbing and mechanical product certification agency
  • IAPMO Platinum Seal™ recipient for exceptional quality and function
  • The average Post may save up to $350.00 per year per distiller in electrical costs versus distillation, with only a fraction of the required maintenance
  • Used at many United States Posts in five continents (references are available)

This 4000 Nanotechnology Certified Under Counter Purification System includes three proprietary filters - 4001 Nano Filter, 4002 Carbon FI Filter, 4003 DE Block Filter and easy to install hardware including a faucet.

When it is time to order replacement filters, the 4010 three pack contains one of each filter shipped in an individual box for easy installation.
